An analysis of hydrophobic fabric using electron microscopy
| Atomic Force Microscopy (AFM) |
| A single thread of the hydrophobic t-shirt was mounted on a stub and placed inside the NTMDT AFM for atomic force microscopy. The biggest challenge faced while imaging with AFM was in landing the tip on a fiber so as to not capture the transition of the tip from one fiber to the other. The set point was kept at a high value of 8 and imaging was carried out at a low gain of 0.1. A scan rate of 0.1 over a small area of 5µm x 5µm provided good results. |
